I'm in my SKScene and I want to unhide a text field in the presenting view controller. I'm using NSNotificationCenter to call a function in my view controller and I've even seen the code arrive at the function and pass the line where the textfield is unhidden, but for some strange reason it doesn't appear. Any thoughts?
Here is the output from the lldb:

I'm having problems tracking down some conflicting constraints. The AutoresizingMask has been added for me, and the other constraint I added in an attempt to understand what is going on:
2015-09-26 22:27:14.959 Darkenss[26537:8462681] Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)
(
"<NSLayoutConstraint:0x7fc461fe9110 UICollectionView:0x7fc463090000.top == UIView:0x7fc461fc6620.topMargin + 302>",
"<NSAutoresizingMaskLayoutConstraint:0x7fc461d3f820 h=--- v=--- 'UIView-Encapsulated-Layout-Top' V:[UIView:0x7fc461fc6620]-(0)-|>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x7fc461fe9110 UICollectionView:0x7fc463090000.top == UIView:0x7fc461fc6620.topMargin + 302>
I don't see how these two constraints are actually in conflict.

Update: I lost the hard drive that project was living on (but I have a backup that was only 45min old, so it'll all work out when I get a replacement...right? I have hope at least). However I have a very big clue.
I was calculating constraints and triggering layout in a KVO observer. This observer was triggering before the view had a superview. Skipping updates that happen before the view has a superview avoid this issue. Thinking about that a little more and:
'UIView-Encapsulated-Layout-Top' V:[UIView:0x7fc461fc6620]-(0)-|
Makes me think the -(0)- is "oh, and the view is zero height, thanks for playing" because said view has no superview and auto layout just doesn't want to deal with that mess.
Hopefully I can get the hardware back in working order early October and find out what is what!
Maybe you have forgotten to set translatesAutoresizingMaskIntoConstraints = NO for some view that you added programmatically on which you are using constraints. That might explain the AutoresizingMask. Kindly check.
UPDATE:
Also, for this constraint:
<NSLayoutConstraint:0x7fc461fe9110 UICollectionView:0x7fc463090000.top == UIView:0x7fc461fc6620.topMargin + 302>
try changing UIView:0x7fc461fc6620.topMargin to UIView:0x7fc461fc6620.top
I am guessing you haven't accounted for the margin while calculating your constant "302"
I am reading code for an app that contains 40+ ViewController. How would you know which ViewController is the current.
What I have tried:
CBIntrospect: execute a UIAlertView with a
message:NSStringFromClass([self class])?
looked at adding
something to NotificationCenter and act on some method when a view
controller is piped?
Using the runtime.h to dynamically add a
method?
Any idea is appreciated
Try this:
- (UIViewController *)topViewController
{
return [self topViewController:self.window.rootViewController];
}
- (UIViewController *)topViewController:(UIViewController *)viewController
{
if (viewController.presentedViewController == nil) {
return viewController;
}
if ([viewController.presentedViewController isKindOfClass:[UINavigationController class]]) {
UINavigationController *navigationController = (UINavigationController *) viewController.presentedViewController;
UIViewController *topViewController = [navigationController.viewControllers lastObject];
return [self topViewController:topViewController];
}
UIViewController *presentedViewController = viewController.presentedViewController;
return [self topViewController:presentedViewController];
}
I often use [self.window recursiveDescription] to print all UIViews through my app. This is not VC, but can be also useful to you.
Just set the breakpoint everywhere you need and type (replace window with your key "UIWindow"):
[window recursiveDescription]
You'll see common result:

I'm trying to show a simple settings screen in my app and I'm using Autolayout. Since my app supports landscape, and the settings controls don't quite fit vertically when the phone is landscape, I added a UIScrollview.
It seems that the combination of UIScrollview and Autolayout is a common question here and elsewhere. I've read a few articles on it, and from what it can tell, it seems that a good way to go for what I'm trying to do is to put my various controls within a view, like a "contentView" with constraints aligned in that view. Then have that contentView be the sole subview of the UIScrollView. I have the contentView with constraints tied to the edges of the UIScrollView.
UINavigationView -> UIScrollview -> contentView (UIView) -> Control Subviews
It works fine in portrait, even if I add content in my contentView that requires scrolling to see, but when I go to landscape, it doesn't let me scroll down far enough. It's like the content size gets reset to the frame of the visible area (or the frame of the navigation controller superview) when I rotate.
I'm wondering if I need to check for rotation and then set the content size again at that time? If so, is there a way to get that size dynamically from the view (contentView)?
Thanks for any help you can offer!

There are two components to having auto layout properly handle scroll views:
Constraints for scroll view's subviews: The contentSize of the scroll view will be dictated by the constraints of the scroll view's subviews. Thus, you need to have a bottom constraint for the last control in the scroll view (i.e. second switch) to its superview (i.e. the scroll view). It looks like you do have this. These constraints for subviews of the scroll view will automatically adjust the scroll view's contentSize as needed.
By the way, the constant for this second switch's bottom constraint will generally default to some largish value corresponding to how it was laid out in portrait. You may want to select and edit this bottom constraint for this last control and change it so that it's the "standard" value.
Constraints for the scroll view itself: You need to make sure you have the bottom constraint for the scroll view, itself, to its superview (and make sure you do not have a height constraint on the scroll view). This will adjust the frame of the scroll view upon screen rotation. I wonder if this might be missing in your project.
You can confirm this by running your app in the debugger, hitting "pause" button:
and then at the (lldb) prompt, type po [[UIWindow keyWindow] recursiveDescription], and you should see something like:

Check the frame of the UIScrollView (e.g. the above is for landscape on iPhone), and make sure it corresponds to the size of screen. If you haven't defined the constraints between the scroll view and its superview, this frame may be incorrect.
Maybe others will have a better solution for this, but the fastest without changing too much on your current build would be to do exactly what you said: check for rotation and then set the content size again.
It would be done like this in your Settings View Controller implementation file:
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
self.scrollView.contentSize = self.contentView.bounds.size;
}
... assuming you have added in that same file outlets to your UIScrollView and your UIView named scrollView and contentView respectively.
On IOS 5.1 I have added a container view to a viewcontroller on storyboard. I want to connect that container view via IBOutlet, so I can manage it easily on IB.
I have tried to use a regular UIView:
#property (nonatomic,weak) IBOutlet UIView *leftView; //connected this to container view on interface builder
then, if I use this, it doesn't work
[self.leftView addSubview:tableVC.view];
If I add a childview controller programmatically it works but it covers full screen of course.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
UIStoryboard* sb = [UIStoryboard storyboardWithName:#"MainStoryboard"
bundle:nil];
UITableViewController *tableVC = [sb instantiateViewControllerWithIdentifier:#"LogMasterViewController"];
[self.view addSubview:tableVC.view];
[self addChildViewController:tableVC];
[tableVC didMoveToParentViewController:self];
}
How can I connect container view to child view controller?
I just tested the following and it works fine:
- (void)viewDidLoad
{
[super viewDidLoad];
UIStoryboard* sb = [UIStoryboard storyboardWithName:#"MainStoryboard"
bundle:nil];
UITableViewController *tableVC = [sb instantiateViewControllerWithIdentifier:#"LogMasterViewController"];
[self.leftView addSubview:tableVC.view];
tableVC.view.frame = self.leftView.bounds;
[self addChildViewController:tableVC];
[tableVC didMoveToParentViewController:self];
}
A couple of thoughts:
If your LogMasterViewController is not a UITableViewController, but rather a view controller with a UITableView on it, you might want to make sure that you don't have autolayout or autosizing constraints on that tableview that make it resize the tableview to something that you can no longer see.
You might want to run the app, pause it after the app has finished presenting the screen (I put a breakpoint in viewDidAppear ... anything after that point should also work too, but don't do viewDidLoad or viewWillAppear) with the LogMasterViewController in self.leftView and then type the following command in the debugger console:
po [[UIWindow keyWindow] recursiveDescription]
You might want to give your leftView and the main view of LogMasterViewController unique tag numbers so you can more easily decipher the output. Anyway, use this recursiveDescription to identify whether the table view has been presented, but simply in a fashion so you cannot see the table, or whether it's not added at all. You can also confirm that your leftView (with its unique tag number, if you gave it one) is there, too.

In this example, I gave my main view of my root controller a tag of "1", leftView has a tag of "2", and the main view of LogMasterViewController has a tag of "3". In this case, these show up as the second, third, and fourth lines of my output (and I also see my UITableViewCells listed below).
The "textboxes" that appear when clicking Tweet or Share for Twitter and Facebook. What are those made of? Can something similar be made? I am trying to customize them so that it will function as "comment" for a tableView. I'm talking of these two:
I am trying to make it say "Comment" instead of "Tweet" and "Facebook".. And then "Done" where it says "Send" and "Post". Any idea how/where I can create/customize these?
These are private view controllers. You can’t (well, shouldn’t) customize them—you’ll have to reimplement them yourself.
You can however, use the private method -recursiveDescription to get an idea of how the view hierarchy’s constructed. Create a simple app that shares some text using UIActivityViewController. Present it, pick Twitter or Facebook, then pause the app in the debugger. Type po [[[UIApplication sharedApplication] keyWindow] recursiveDescription] into the console to list the current view hierarchy.
EDIT: Ok, I was curious…

Basically, it’s what you’d expect: a bunch of background images, a label and buttons to fake the navigation bar style and a big text view for content.
